Concrete can be classified according to its use into structural concrete, mass concrete, waterproof concrete, heat-resistant concrete, expansive concrete, radiation-proof concrete, road concrete, etc.

[0003] The existing Chinese patent (Announcement No.: CN213918893U) mentions a pre-mixing mechanism for a concrete mixer, which relates to the field of concrete mixing technology, specifically a pre-mixing mechanism for a concrete mixer, including a mixing box and a feeding box, wherein a mixing box support leg is fixedly connected to the bottom of the mixing box, a connecting plate is fixedly connected to one side of the mixing box, a connecting plate support leg is fixedly connected to the bottom of the connecting plate, a feeding port is provided on one side of the feeding port, and a box cover is hinged on one side of the feeding port.

[0004] When the concrete material enters the mixing box, the driving motor is used to drive the rotating rod, and the rotating rod drives the stirring rod to stir the material in the mixing box. When the stirring rod stirs the material, the stirring direction is relatively single, and the mixing time may be long when stirring the material, and the mixing may be insufficient. Utility Model Content

[0005] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that the stirring direction of the stirring rod when stirring the material is relatively single, which may result in a long mixing time and insufficient mixing. The present application provides a stirring device for a concrete mixer.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A mixing device of a concrete mixer comprises a mixing chamber, a support frame is fixed on the mixing chamber, a discharge port is provided at one end of the mixing chamber, a driving motor is fixed at one end of the mixing chamber away from the discharge port, a mixing mechanism is provided in the mixing chamber, a feed pipe is provided on the mixing chamber, and a feed mechanism is provided on the feed port;

[0008] The stirring mechanism includes a stirring shaft rotatably connected in the stirring chamber, the output end of the driving motor passes through the stirring chamber and is fixedly connected to the stirring shaft, a stirring auger is fixed on the stirring shaft, rotating shafts are provided on both sides of the stirring shaft, connecting rods are rotatably connected at both ends of the rotating shaft, the connecting rods are fixedly connected to the stirring shaft, an auxiliary auger is fixed on the rotating shaft, and a reversing component is provided at one end in the stirring chamber.

[0009] By adopting the above technical scheme, the material is evacuated by using the feeding mechanism, and then the feeding mechanism is opened. The material in the feeding mechanism directly passes through the feeding pipe into the mixing bin, and then the driving motor is started. The driving motor drives the stirring mechanism to stir the material in the mixing bin while pushing the material in the mixing bin to move back and forth, so that the material added to the mixing bin can be more uniform, thereby improving the stirring effect, making the material mixed more uniformly, and reducing the time spent on sufficient stirring; the stirring auger pushes the material in the mixing bin and drives the connecting rod at the same time. The connecting rod drives the rotating shaft, and the rotating shaft rotates around the stirring shaft to stir the material. The rotating shaft rotates under the action of the reversing component, so that the rotation direction of the auxiliary auger is opposite to that of the stirring auger, so that the material in the mixing bin can be stirred while the material in the mixing bin can be pushed back and forth, thereby improving the effect of stirring the material.

[0010] Furthermore, the reversing assembly includes a gear ring fixed in the mixing chamber, two gears are meshedly connected in the gear ring, and the two rotating shafts are fixedly connected to the corresponding two gears.

[0011] By adopting the above technical solution, the rotating shaft drives the gear to move on the gear ring. When the gear rotates on the gear ring, the rotation of the gear drives the rotating shaft to rotate, and the rotating shaft drives the auxiliary auger to rotate, so that the auxiliary auger can also rotate conveniently.

[0012] Furthermore, a protective shell is rotatably connected to the gear ring, the rotating shaft passes through the protective shell and is rotatably connected to the protective shell, and the stirring shaft passes through the protective shell.

[0013] By adopting the above technical solution, when the rotating shaft rotates around the stirring shaft, the rotating shaft drives the protective shell to rotate, thereby reducing the possibility of materials entering between the gear rings.

[0017] By adopting the above technical solution, the material is poured directly into the feed pool, and the dust cover 1 and dust cover 2 cover the feed pool. Then, the material in the feed pool is spread out using the evacuation component, so that the material can enter the mixing bin evenly, thereby improving the mixing effect of the material in the mixing bin and reducing the dust generated by the flattened material.

[0018] Furthermore, a sliding rod is fixed on one side of the feeding pool, a threaded rod is rotatably connected to the side of the feeding pool away from the sliding rod, a servo motor is fixed on one end of the feeding pool, and the output end of the servo motor passes through the feeding pool and is fixedly connected to the threaded rod.

[0019] By adopting the above technical solution, the servo motor drives the threaded rod to rotate back and forth, so that the material can be easily spread.

[0020] Furthermore, a support rod is threadedly connected to the threaded rod, the threaded rod penetrates the support rod, one end of the support rod away from the threaded rod is slidably connected to the sliding rod, and evenly distributed evacuation teeth are fixed to the support rod.

[0021] By adopting the above technical solution, the support rod drives the evacuation teeth to move back and forth, and then the evacuation teeth flatten the material in the material teeth, thereby reducing the possibility of the material being poured into the mixing bin and piling up.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. In the present application, when the material enters the mixing chamber, the driving motor drives the mixing shaft to rotate, and the mixing shaft drives the mixing auger to rotate, so that the mixing auger pushes the material in the mixing chamber, and at the same time, the mixing shaft drives the connecting rod, and the connecting rod drives the rotating shaft, and the rotating shaft rotates around the mixing shaft to mix the material. When the rotating shaft rotates, the rotating shaft rotates under the action of the reversing component, and then the rotating shaft drives the auxiliary auger to rotate. The rotation direction of the auxiliary auger is opposite to that of the mixing auger, so that the material in the mixing chamber is pushed back and forth, and the material is mixed in the mixing chamber, thereby achieving the purpose of being able to stir the material in the mixing chamber while allowing the material in the mixing chamber to be pushed back and forth, reducing the time spent on sufficient mixing of the material and improving the effect of mixing the material.
